SV 104A Noise Dosimeter

New!

The SV 104A is a new personal noise dosimeter with a Bluetooth® communication supported by the Smartphone application called Assistant. For measurements of noise at work in accordance to ISO 9612 as well as OSHA, MSHA and ACGIH standards all settings are configurable in the PC software and can be stored in the dosimeter memory as setup files that can be selected directly from the dosimeter keyboard.

The dosimeter has a very robust MEMS microphone that has a lifetime warranty. All vibrations that affect noise measurement results are detected by an inbuilt tri-axial vibration accelerometer and are marked in the results time history, so they can be easily excluded from dose calculations. Additionally, the accelerometer detects if dosimeter is not used by the worker and marks this information in time history. We have designed the SV 104A to make noise dosimetry measurements easier. Firstly, the voice comment feature replaces necessity of identifying the dosimeter with a different type of stickers. Secondly, a single large measurement range of 53 dB to 141 dB enables measurement in all kinds of working environment. But mostly, the auto-calibration is what makes the SV 104A easy in use. Once the SV 104A detects a calibration signal, it calibrates automatically saving the calibration data together with the measurement file, before and after measurement. The list of distinguishing features of SV 104A includes a color OLED display that can be easily read even in a full daylight or in the dark. The user interface is very friendly to use which makes setting up and using the instrument easier than ever. The user may choose from multiple setup files that can be configured through the included "Supervisor" software. All measurement data are stored in the integral 8 GB memory which provides a vast amount of storage.

Standard Kit

The standard SV 104A kit includes ST104A shock resistant MEMS microphone, windscreen with a steel mounting thread and a USB cable for communication with PC. The instrument has an inbuilt 8 GB memory and a long-range Bluetooth interface for communication with Assistant application. Each SV 104A has its factory calibration certificate, 36-MONTH WARRANTY CARD and LIFE-TIME WARRANTY card on MEMS microphone. The standard kit also includes license for PC software and Assistant application for smart-phones.

Optional Functions

The option for 1/1 and 1/3 OCTAVE real-time analysis allows accurate and correct selection of hearing protectors. When presented as a spectrogram, the frequency analysis can be used for a quick verification of noise sources in the time history. It can be activated at any time, by entering an activation code.

The AUDIO EVENTS RECORDING option works during measurement and is logged in parallel to time history so it can be played back in the PC software. The settings, like triggers or recording time, are adjustable. It can be activated at any time, by entering an activation code.
